From 5c01b46bb6bb8f2662573c05c87b5d68fa25af89 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 13 May 2009 22:56:36 +0000 Subject: asm-generic: add generic NOMMU versions of some headers Memory management in generic is highly architecture specific, but on NOMMU architectures, it is mostly trivial, so just add a default implementation in asm-generic that applies to all NOMMU architectures. The two files cache.h and cacheflush.h can possibly also be used by architectures that have an MMU but never require flushing the cache or have cache lines larger than 32 bytes.
